Nutritionists, wellness experts or biohackers will often say that the scales are not always the best way to tell if you are making progress towards your weightless and fitness goals. Possibly a better way to tell if you're on the right track is how you feel, how your clothes fit, and how you look in the mirror. Taking advantage of the current selfie craze is a new app called Progress.​Progress lets you track your weight loss or fitness progress by taking daily selfies that are perfectly aligned. The idea is that the app creates a faint outline of your selfie from the mirror and allows you to line yourself up exactly the next time. After 15 days the app shows you a time lapse video of the changes to your body shape. Pretty cool idea that also syncs to the Apple health kit.
